There is still plenty of decision making. For any scramble, there are usually a few dozen ways that make sense to make a cross. A top cuber may choose a slightly slower way to do the cross to make the first f2l pair easier (or even solve the first pair at the same time as the cross). They may choose an unusual way to insert the second f2l pair to make the third pair easier. There are a handful of videos out there of cubers breaking down their solves and explaining their decisions.

The last layer doesn't really have any decision making though.
